  • Commented on Ask me anything!
    The build quality of most store bought clothing is terrible for a very simple reason: Most of it has terrible sell-through. The store orders home a hundred pieces, and sells, perhaps, 20 of those before fashion moving on forces it...
  • Commented on Ask me anything!
    The Java virtual machine is a lot more efficient than it used to be - It matches up pretty well with c/c++ these days, especially for larger software, since it automatically inlines things efficiently, which is something that gets done...
  • Commented on Story time!
    Oh, I was not talking about the voters. I was talking about the people actually occupying elected positions. Note that to ensure as little defection from this equilibrium as possible, the day to day lives of senators and congress people...
  • Commented on Story time!
    That is inherent in the ideology. Look, anyone who would do an actual good job of governing has a skill-set the private sector would pay them millions a year for. To get them into politics, they have to be idealists...
  • Commented on Story time!
    Given the incident with the colliding boomer subs, I suspect that the whole issue of "Reactor noise" might be... slightly overstated for modern designs....
  • Commented on Story time!
    Carriers have the approximate radar signature of a city. Sure, the f-35 staging of it is stealthy, but you do not have to hit it -just the enormous floating target. Carriers have very fancy anti-air and anti-missile defenses because this...
  • Commented on Story time!
    Sigh. Productivity is resilience. You are envisioning doing things by hand as less likely to fail, but the problem is, doing this sort of labor by hand easily quadruples the caloric intake of the people doing the work, and "Enough...

    Re: Kilns. Thing is.. if you are doing small batch steel production, you do that with electricity. Unto the end of time. Seriously, it is just a lot less effort and land use that way. Village of a hundred people?...
  • Commented on Story time!
    Did you follow the link to the micro-wave iron smelter earlier in the thread? Because that was hilarious, though the professor is barking up the wrong tree if he wants it commercialized - Sweden will be all over that process....
  • Commented on Story time!
    Uhm. Assuming a situation where anything that floats on the surface in international water gets explosives dropped on it by long range bombers as a result of "the War on Trade" what goods are compact enough to be worth hauling...
  • Commented on Story time!
    Keeping an existing chip fab going is very cheap, as compared to building them. This is why old generation chips end up costing next to nothing. Which. Heh. Hilarious plot: Global trade collapses into smaller chunks, at least in part...
  • Commented on Story time!
    .. Re those drones of world unmaking. I look at those, and go... "Reactor fuel!" I mentioned fast spectrum molten salt machines? Well, starting the first generation of those up needs high enrichment mixes (They can be strong breeders, so...
  • Commented on Story time!
    Again. The electricity will be kept on even if we are all starving. People will literally feed the plant staff their dead before they let the power fail. Because without electricity, what food there is will spoil. And because fertilizer...
  • Commented on Story time!
    And it was back up in less than 24 hours. People are not predicting transient outages, they are predicting a future without, or with very scarce, electricity, and that is bonkers. I see it predicted constantly, and it does my...
  • Commented on Story time!
    Oh, for. This again. There is a conversation attractor in all conversations about the future where energy starvation is just taken as a given, and it is insane. This is not a future that can happen. The power will stay...
  • Commented on Social architecture and the house of tomorrow
    Unpacking things: There is a concept very popular with a certain faction of the "We are All Doomed" crowd called Energy Return on Energy Invested, with an accompanying argument that civilization is fundamentally reliant on energy sources which have a...
  • Commented on Social architecture and the house of tomorrow
    Still, the bound is going to hold. Diesel at the mine head is not going to be cheaper than electricity at the reactor gate, even if you pretend one hundred percent of mining costs are energy. Which was the lazy...
  • Commented on Social architecture and the house of tomorrow
    Nuclear has sky high EROEI, very much including waste disposal. It is trivial to prove this. Step one: Note that there does not exist any charities donating diesel and electricity for free to the mining consortia of the world. Nor...

    Spain does not actually have a lot of rebuild examples to get costs of - but they do manage to build highspeed rail for below 7 million euro/km fairly often despite the need to ram those lines through mountains on...
  • Commented on Social architecture and the house of tomorrow
    It does include things like "And a third of this rail line is in tunnels" so.. you could just bore your way under London....
  • Commented on Social architecture and the house of tomorrow
    Wait, no, that was the electrified length. It is only enough money to rebuild the whole network once....
  • Commented on Social architecture and the house of tomorrow
    65 billion with sane planning and contracting should get you... up to eleven thousand kilometers of high speed rail (cost of best practices in Spain). That is not a math error. You have allocated enough money to this problem to...
  • Commented on Social architecture and the house of tomorrow
    Fusion research more than anything else seems to be about the exploration of plasma physics, for both military and scientific reasons - That is, some of the funding is there because if you understand the process well enough, you can...
  • Commented on Social architecture and the house of tomorrow
    Most proposals to use ammonia as fuel do not envisage lighting it on fire - it is mostly considered as a convenient way to store hydrogen to run fuel cells on. or directly fed to fuel cells. Either way, that...
  • Commented on Social architecture and the house of tomorrow
    ... EROEI is a pseudo-statistic that does not matter much for prices, but to the extent it is a thing, nuclear wins. Nuclear has better energy return than just about anything else, and it has been rising quickly in recent...
  • Commented on Social architecture and the house of tomorrow
    ... Again, electricity scarcity is never going to be a thing. It is not a thing that can happen. Liquid fuels? Those can get pricy, though that too has limits - for one thing, ammonia synthesis is trivial. But electricity...
  • Commented on Social architecture and the house of tomorrow
    ... *Wicked grin* I mentioned before that Spain demonstrates infrastructure can be done far cheaper than you imagine possible? Well, one of the things they do well is tunnels. On top of that, tunneling is obviously a problem which superior...
  • Commented on Social architecture and the house of tomorrow
    This is not a possible future. If mechanized food production goes away, gigadeaths follow. Not because of food shortages, exactly, but because the general collapse of economic productivity implied by that means nothing else gets done, and that is not...
  • Commented on Social architecture and the house of tomorrow
    Eh. This is entirely a urban myth. https://www.howtogeek.com/231886/tested-should-you-unplug-chargers-when-youre-not-using-them/ The power draw of chargers not in use is effectively nil....
  • Commented on Social architecture and the house of tomorrow
    About the only firms that even consider doing this now are pressure cookers. Productivity research, ca 1920, 1930. Workers cant sustain output for more than about 40 hours a week, long term. Footnotes to said research, post 2000: The actual...
